A system for propelling a vehicle which includes a frame within which at least one shuttle is mounted for reciprocal movement along a linear path of travel. An oscillating body is attached to the shuttle that is capable of delivering a series of alternating opposed force pulses to the shuttle with the pulses acting in a direction generally along the shuttle's path of travel. A rectifying means periodically locks the shuttle to the frame when the force pulses act in a first direction whereupon the forces are transmitted to the frame and unlock the shuttle when the forces act in the opposite direction, whereupon the shuttle is caused to move in the opposite direction. A return mechanism is operatively connected to the shuttle for restoring the shuttle to its original starting position after it has been driven a predetermined distance over the path of travel.
